JavaFX 多重转换
我们可以利用节点上所有变换的综合效果。为此,JavaFX 提供了addAll(Transform obj1, Transform obj2....)方法,该方法可以在<node-obj>.getTransforms()方法返回的引用上匿名调用。
以下示例在矩形上实现所有转换。
多重转换的例子
以下示例说明了对对象的所有转换的实现。在这里,我们创建了一个矩形并对其应用了平移、旋转、缩放和剪切等变换。
package com.yiidian;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.scene.shape.Rectangle;
import javafx.scene.transform.Rotate;
import javafx.scene.transform.Scale;
import javafx.scene.transform.Shear;
import javafx.scene.transform.Translate;
import javafx.stage.Stage;
public class MultipleTransformations extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
//creating Rectangle and circle
Rectangle rect = new Rectangle(50,10,200,250);
Circle c = new Circle(300,260,100);
//setting properties for the rectangle and circle
c.setFill(Color.LIGHTBLUE);
c.setStroke(Color.BLACK);
rect.setStroke(Color.BLACK);
rect.setFill(Color.LIMEGREEN);
rect.setStrokeWidth(2);
//creating the translate transform
Translate trans=new Translate();
trans.setX(100);
trans.setY(10);
//creating Rotate transform
Rotate rotate = new Rotate();
rotate.setAngle(30);
rotate.setPivotX(50);
rotate.setPivotY(100);
//Creating Scale Transform
Scale scale = new Scale();
scale.setX(1.5);
scale.setY(1.2);
scale.setPivotX(50);
scale.setPivotY(50);
//creating Shear Transform
Shear shear = new Shear();
shear.setX(0.3);
//applying all the transforms to the rectangle
rect.getTransforms().addAll(trans,rotate,scale,shear);
Group root = new Group();
root.getChildren().addAll(rect,c);
Scene scene = new Scene(root,550,500);
primaryStage.setScene(scene);
primaryStage.setTitle("一点教程网:Multiple Transformation Example");
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
